the immediate ancestor of european chess is the perso-arabic game of šaṭranj (شَطْرَنْج), which developed out the indian game of caturaṅga (चतुरङ्ग) probably around the 7th century ce, and crossed into sicily and al-andalus from the maghreb around the 10th century. the name of this game gives the name of chess in the ibero-romance languages eg spanish ajedrez, portuguese xadrez (from old portugues axadrez); typical of arabic loans into ibero-romance, the arabic definite article aš- has been reinterpreted as part of the word. the words in the germanic (english chess, german schach), italian (scacco), gallo-romance (french echeque, catalonian xec), and slavic languages (russian шахматы šakhmaty, polish szachy) instead come from the persian word šâh, 'king', in the expression šâh mât, literally '(the) king (is) amazed' but reinterpreted in arabic to mean 'the king is dead', whence also 'check' and 'checkmate'
I guess one of the ways is to salvage from dud stuff :-P
Here is what I suspect:
1. Operating at 3.3V is causing issues
2. The mounting area walls are inside the cone (75deg)
3. The board is dud
Should be able to verify all the points in a week.
It might be a bad daughter board too. Let's see.
I guess running the JSN-SR04T v3.0 on 3.3V "just won't work".
You won't believe this but my initial suspicion was that AC power lines were causing bad data signals through the sensor. Doesn't seem to be the case.
well, liquid flow sensor
And now I notice that enabling virtio-scsi causes data corruption in the VM. Great.
Turned out "alright". I might tune it to reduce stringing, but it's not much, so 🤷🏻♂️
